Application filed December 13, 1913. Serial No. 806,596.

To all whom it may concern Be it known that 1, JAMES F. CRAVEN, resident of Grafton, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Receptacles for Containing and Discharging Semisolid and Pasty Substances, of which the following is a specification.

This invention relates to receptacles for 1 containing, storing, transporting and discharging semi-solid and pasty substances.

The receptacle is intended for putting up such substances as lubricating grease, soap,

Vaseline, medicated greases, butter or other like food stuffs, cosmetics, etc., in hermetically sealed packages of convenient size for handling, packing and transporting, and adapted to deliver the contents therefrom in any desired quantity or quantities.

One object of the present invention is to provide a receptacle embodying a movable follower for expelling the material, in which the operating mechanism for the movable follower is arranged so that when operated it forms an opening or orifice in the container, through which the substance is expelled by further operation of the p1ston.

A further object of the invention is to provide a receptaclein which the follower is moved by a flexible band wound upon a key, and wherein the winding key or band when operated ruptures a portion of the wall of the container to form a discharge orifice through which the material is expelled or otherwise opens a discharge orifice, the several ports being so arranged that the size of said orifice is independent of the width of the winding band.

A further object of the invention is to produce a receptacle of the character described, which may be hermetically sealed easily and without liability of introducing the sealing material, such as solder, into the contents of the receptacle.

A further object of the invention is to produce a receptacle having a weakened portion which is ruptured or removed by the act of winding up the winding band to move so the follower, thereby producing a discharge orifice for the receptacle.

A further object of the invention is to provide an improved form of follower, arranged so that when operated 1t dlscharges the entire contents of the receptacle.

Other objects of the invention are in part obvious and in part will appear more in detail hereinafter.

In the drawings Figure 1 represents a longitudinal sectional view of one form of receptacle embodying the invention; Fig. 2 is an end view thereof; Fig. 2 is an enlarged detail section on the line 0c00 Fig. 2; Fig. 2 is an enlarged detail view showing a modification; Fig. 3 is an end view of another embodiment of the invention; Fig. 1 is a detail sectional view thereof; Fig. 5 is a detail view, illustrating a modification; Fig. 6 is a sectional view, showing another form of the invention; Figs. 7 and 8 are re spectively detail sectional and end views of another form ofthe invention; Figs. 9 and 10 are end views showing other embodiments of the invention; Figs. 11 and 12 are longitudinal sectional views illustrating modifications; Fig. 12 is a detail View showing the operation of the form illustrated in Fig. 12; and Fig. 18 is a detail view of a Winding key.

A feature which is characteristic of most forms of the invention is the fact that the receptacle is not initially provided with a discharge opening or orifice which is scaled up after filling the receptacle and is merely opened or uncovered by operation of the follower moving means, but said means when first operated actually forms or creates the orifice, by rupturing or tearing the material of which the receptacle is formed.

Referring to the drawings, the container shown in Figs. 1 and 2 embodies a casing 1 comprising a side wall and two end caps or heads closing the ends thereof. It may be of any shape in cross section, such as round or square, and may be formed of any suitable material, such as paper, wood or metal, but preferably is formed of thin sheet metal for a reason which will appear hereinafter. The end caps or heads are secured to the side wall in any suitable manner, and when the receptacle is formed of sheet metal, they are preferably secured by a crimping or beading operation, the receptacle being filled before securing the second end cap or head thereto. The material is expelled from the receptacle by a follower 2 operated by a flexible band or connector 3 which is wound upon a suitable key 4; of a common form.

In the form shown in Figs. 1 and 2 the ceptacle. The end cap or head may be provided with a weakened portion 7 in any suitable manner, such as by cutting only part way through the metal, or merely creasing the same, as shown at 20, Fig. 2", or by a cupping or drawing operation which presses outwardly from the metal a boss or enlargement having weakened sides 7*. The weakened portion may be of any preferred shape, for example, long and narrow as shown in Fig. 2, but may be wider than the band 3.

The band 3 is bent down into contact with the; outer surface of the end cap and lies over the weakened portion 7 thereof. to

which it is connected, as by solder 8. Ihe extreme end portions of the band are left free to form a lip or tongue 9, to which the winding key 1 is applied. The opening 5 through which the band extends is securely sealed with solder, as indicated at 10.

In use of the receptacle the winding key 4 is applied to the lip 9 and the band 3 is wound thereon. The weakened portion 7 of the end cap or head ruptures or tears loose as the windingoperation proceeds and forms a discharge opening,'as will be readily understood. When that portion of the V band outside the receptacle is entirely wound up on the key and the solder 10 which seals the opening 5 is torn loose, further rotation of the winding key draws thefollower 2 through the receptacle and eXpels the terial from the discharge orifice. Under some circumstances it'may be unnecessary to weaken the material of the cap as it may tear out or rupture without this. feature. The band 3 may pass directly through the weakened portion of the receptacle, as shown in Figs. 3, 4 and 5. In this case the end of the winding band outside of the receptacle is not soldered to the fiat outer face of the end cap or head, but the opening or slot 'through which it passes is merely sealed with solder 10. The winding key is applied to the free end of the band, which. is wound thereon. The key is split longitudinally, to provide an opening for receiving the band, by a shearing operation which splits the shank and forces the two side portions thereof past each other forming lateral projections, as shown at 11. These projections 11 form cams, which are forced down against the weakened portion 7 a by I the winding operation and collapse one side of the same inwardly, thereby forming the discharge orifice. The portion of the end cap torn off is of thin metal and winds up onthe key with the band. In this form of the invention the discharge orifice produced may be of any preferred shape and is shown as round in Fig. 3.

In Fig. 5 the weakened portion 7", which is torn off to form the orifice is of modified \/-shape with the opening for the band near the wide end. This form of opening enables the material to be discharged nearer the side wall of the receptacle.

In Fig. 6 the receptacle is punched out-- wardly to provide a boss or protuberance T which is provided with a single side opening 5 for the winding band. When the band is wound upon the key the weakened portion 7 is ruptured to produce the discharge opening.

The winding band 3 in Figs. 7 and 8 passes out through a central opening 5 and is bent laterally and passes through openings 5 in the sides of the boss or protuberance 7 forming the weakened portion of the receptacle. The several openings 5 and 5 are all sealed with solder. This form of the invention is a little more positive in action than some of the forms above described, as the winding band lies under the wealmned portion of the receptacle and the latter must necessarily be torn off before the piston is operated. There is no liability of the band tearing loose without producing a discharge orifice.

Fig. 9 shows a receptacle in which the weakened portion 7 comprises a separate member, shown as a metal disk, which is soldered to the receptacle over a discharge orifice 12. This orifice is preferably near one side of the receptacle and the .vinding band comes out through an opening 5 in the middle of the end cap or head. The band passes through a slot in a tongue of the disk 7 so that there is a strap 21, integral with the disk '7 which lies over the winding band. lVhen this band is wound up the disk 7 is progressively torn free from the receptacle to expose the orifice 12. The orifice 12 may be of any suitable size, which does not depend upon the width of the winding band, and is shown in Fig. 9 as considerably wider than said band. The band need not therefore be as strong or of such heavy material as is necessary when substances of this kind are discharged through a small orifice. The disk 7 need not be a separate disk soldered to the receptacle, but may be a weakened portion thereof, as shown at 7, Fig. 10.

In all the forms described, the winding band is double and is attached to the center of the piston 2 and in suitable manner, as by looping it therethrough, as shown in Fig. 1, with the two strands of the band folded together.

In Fig. 11 the winding band has two strands and is looped through two openings 6 at opposite edges of the follower. The

two strands pass out through oppositely disposed openings 5' in the end cap or head and are bent toward each other and have their free ends adjacent to form a lip or tongue 9 for the winding key. The openings 5 are sealed with solder, but no solder is applied to the contacting surfaces of the end cap or head and the exposed ends of the band 3. When said band is wound up on the key, force is applied to the material of the end cap or head at both of the soldered openings 5 and portions of the end cap are partially sheared out as indicated by the dotted lines, so that two discharge openings are formed.

In Fig. 12 the winding band is of the same form shown in Fig. 1, but passes through two separated openings 5 so that when operated a portion at the center of the end cap is sheared or partly sheared out and rolls up as in Fig. 12 to form the discharge opening.

The follower may be of any suitable form, but preferably comprises a hollow cylinder 13 loosely fitting the inner wall of the receptacle and which is moved along the same by a head 14:, shown as a solid disk with its periphery lying inside of the cylinder 13. The cylinder 13 and disk head 1 1 are socured to each other by a suitable frangible connection, which may be formed by suitable adhesive applied between the periphery of the disk and the inner surface of the cylinder 13, or may consist of a sheet of paper glued to the back of the disk 14 and having its periphery glued to the back end of the cylinder 13, as shown at 15. At the end of the follower stroke the advancing end of the cylinder 13 strikes a suitable abutment, which may, for example, be a portion of the end cap or head toward which it moves, whereupon the frangible connection between the cylinder and disk breaks and the disk moves through the cylinder. The cup form of follower is effective to expel the material and the construction described enables such a follower to be used, without sacrificing any of the space within the receptacle.

In any of the forms described air may be admitted to the space behind the follower in any suitable manner, as through a small puncture in the bottom end cap or head.

All the forms of the receptacle described are simple and may be constructed and filled at low cost. A key is furnished with each receptacle so that by applying the key the user may open the receptacle and expel its contents in any suitable quantity or quantities. At the same time the material is put up in hermetically sealed form and is not liable to deteriorate or to be contaminated before used.

What I claim is:

1. A device of the character described, comprising a receptacle having a body or wall formed of sheet material, a follower therein, and means for operating said follower, said means being arranged when operated to first rupture or tear the original sheet of the body or wall and thereby form a discharge orifice and then move the follower to expel the contents of the receptacle through said orifice.

2. A device of the character described, comprising a receptacle having a body or wall formed of sheet material and having a portion thereof weakened along a line, a follower therein, and means for operating said follower, said means being arranged when operated to rupture or tear the original sheet of the body or wall along said weakened line and thereby form a discharge orifice and then move the follower to expel the contents of the receptacle through said orifice.

3. A device of the character described, comprising a receptacle having an abutment at its discharge end, a follower movable therein, and means for moving said follower, said follower comprising a hollow member arranged to move along the receptacle wall and engage said abutment, a disk, and a frangible connection between said disk and hollow member and adapted to be broken when said hollow member engages said abutment.

4. A deviceiof the character described, comprising a receptacle having an abutment at its discharge end, a follower movable therein, means for moving said follower, said follower comprising a cylinder and a disk lying within said cylinder, and a frangible connection between said disk and cylinder arranged to permit the disk to move through said cylinder when the latter impinges against said abutment.

In testimony whereof, I have hereunto set my hand.
